The effect of properties like density, viscosity and flashpoint with alcohol additives in biodiesel blend fuel has been studied. Biodiesel blend fuel (B20) is used for characterization to compare with 5% and 10% of ethanol and methanol. The results indicated that flash point of B20 decrease drastically at 5% alcohols and increases at higher percentages. Increase in flash point as blend concentration increase may be considered better with respect to safety in fuel handling. In case of viscosity...

This study aims to use "AERBETON" which is an air entraining material added to the concrete mix to take advantage of its properties in construction in Gaza Strip. Through this work, AERBETON, which is an air entraining material, was used as an additive to concrete mixture. The purpose is to study its properties when added to concrete before and after hardening, as well as comparing the results with concrete having the same ingredients but without adding this material. In general, the...

The Emissions Reducing program related to Deforestation and Forest Degradation (Redd +) calls for the development of approaches to quantify and spatialize forest carbon in order to design more appropriate forest management policies. The mapping of carbon stocks was done in the Wari-Maro Forest Reserve. To achieve this, forest inventory data (in situ) and remotely sensed data (Landsat 8 image) were used to construct a wood carbon stock forecasting model. Simple linear regression was used to test...

In order to study the effects of herbivory on plant communities, we determined whether the types and concentrations of chemicals present in different aspen (Populus tremuloides Michx.) stands and understories, i.e., the foodscape, are associated with aspen use by elk (Cervus elaphus L.) and with aspen regeneration and recruitment. Transects were established in aspen stands with high, medium, and low regeneration levels (N=5 locations/regeneration level; ranging from 2,331 m to 2,724 m in...

C. albicans is a commensal yeast which asymptomatically colonizes mucosal surfaces; however, any disruption in the host environment or under conditions of immune dysfunction, C. albicans can proliferate and invade virtually any site in the host. S. cerevisiae is found in nature associated with man and, more rarely, found on the skins of grapes. S.bayanus can be found in locations remote from humans, which is not in common with S. cerevisiae . H. anomala ecological traits include: fermentation...

Several computational chemistry programs were evaluated as aids to teaching a part of qualitative analytical chemistry. Computational chemical calculations can predict absorption spectra, thus enabling the modeling of indicator dissociation mechanisms using a personal computer. An updated MNDO program among 51 programs was previously found to be the best predictor to explain the dissociation mechanisms of isobenzofuranones and sulfonephthaleins. Therefore, the further quantitative analysis was...

In this paper, we provide the solution of a modeled parallel resonant circuit using the decomposition method. The parallel resonant circuit also known as resistor (R) in ohms, inductor (L) in Henry and capacitor (C) in farads (RLC) circuit is used in turning radio or audio receivers. The mathematical models are in a system of ordinary differential equations (ODE), which we solve using the Adomian Decomposition Method (ADM). We discovered that this method gave exact solutions as can be obtained...

During the pre-monsoon months in Nepal, severe thunder and hailstorms cause significant property and agricultural damage in addition to loss of life from lightening. Forecasting thunderstorm severity remains a challenge even in wealthy, developed countries that have modern meteorological data gathering infrastructure, such as Doppler Radar. This study attempts to isolate the specific and unique characteristics of the two hailstorms that might explain their severity. The primary data sources for...

The study analyzed the occupational health hazards of fish smoking among fisher-folks in the coastal areas of Ondo State, Nigeria and further proffered strategies for their management and control. Fish smoking combines the effects of drying, heating, and smoking coupled with salting. The pre-treatment involves gutting, splitting and smoking using firewood. Smoking is the oldest, convectional and most common methods used where the heat from the fire dries the fish while chemicals from the smoke...

It is significant to use renewable resources to maximize crop yields and minimize the environmental risks accompanying with chemical residues. Composting is an age old practice for the biological conversion of organic waste into a humus-like substance which can enhance physical, chemical and biological soil properties. Vermicomposting of leaf litter by Eisenia foetida and Eudrilus eugenia potentially play a substantial role in remediation of organic waste as well as building up of soil...

Anthurium is one of the important economic cut flowers all over the world. One of the most important problems in the production and sale of cut flowers is their vase life after their separation from the plant. A good solution for holding cut flowers must contain antimicrobial materials and nutrients. B is an element that is not in fungi and bacteria, therefore, its high levels are toxic to them. Sucrose can also be a source of energy for cut flowers. Our aim is to use Sucrose and B properties...

The mechanical conformation is widely used in metal materials manufacture, being the bending process one of the most applied in the metal-mechanical industry. The material behavior analysis is important in this kind of process, since fabrication problems can compromise the final performance of bent components. During the bending process of metal sheets, the sheet undergoes a geometric variation after the withdrawal of the load. This effect, as known as elastic recovery, can be harmful when it...
